How do I make a synced cloud variable

[nova light]

you can use event sender that target "ALL", this will apply the same value of cloud variable for each player in the room

or if you use trigger volume you can edit the circuit board of trigger volume and remove "if local player should run"

this make the trigger volume only runs for authority of the trigger volume

yep

yea, Config the target to "ALL"

you need event receiver

ig no

yes
